Answer:
B
Explanation:
Darker colors such as red and orange represent warmer temperatures and lighter colors such as green represent cooler temperatures
Northeastern USA has a lot of lighter colors meaning that it's cooler in the northeast
Southwestern USA has a lot of darker colors meaning that its warmer in the Southwest.
If you were to draw from southwest to north east temperatures would decrease as it's cooler in the northeastern areas.
Therefore we can conclude that B is the correct answer.
